Can advertising or product names make a product "medicinal"?

Are there any products which might on the face of it seem to qualify as licensable medicinal products but are exempted?

How do I avoid the "medicinal product" risk?

Are there any particular words I should avoid to escape the "medicinal" trap?

Assuming I have a licensed "medicinal" or a "medicinal product" such as a cosmetic which is exempt from licensing, are there any other rules that apply to its advertising?

What about health foods?
